Microphones Procurement Notes

Verify the specific suffix 'ABC-3' against the manufacturer's latest documentation to confirm pinout and electrical characteristics. Check for obsolescence status as this component may be discontinued. Ensure compatibility with existing board layouts regarding the specified 0.236-inch diameter and pad termination style before finalizing procurement.

Microphones Selection Notes

Select this microphone when an omnidirectional response is required for general-purpose voice capture. The 2V to 10V operating range offers flexibility in power supply design. Consider the 60dB SNR and -42dB sensitivity for applications requiring clear audio transmission in moderate noise environments. Verify that the 100Hz to 10kHz frequency response aligns with the target application's bandwidth requirements.

Microphones Part Context

This component belongs to the MD series of microphones manufactured by Knowles. It is part of a family of analog electret condenser microphones designed for compact audio applications. The MD series typically offers various sensitivity levels and form factors to suit different consumer electronics needs.

Microphones Replacement Considerations

Consult official substitution guides for equivalent models within the MD series or other omnidirectional electret microphones with matching sensitivity and impedance specifications.
